Machines for the manufacture of constructional products from concrete and calcium-silicate - Safety - Part 1: Common requirements
This European Standard applies to machines for the manufacture of constructional products from concrete and/or calcium silicate examples of which are listed in annex A of this part. It gives concepts and general and common requirements for the design, operation and maintenance of such machines. !This European Standard deals with hazards listed in Clause 4 which can arise during the operation and maintenance, including the interfaces, of the machines for the manufacture of constructional products from concrete and calcium silicate, when carried out as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. Part 2 to 8 of this standard give additional specific requirements and therefore have to be applied together with this part. The preparation of concrete and/or calcium-silicate mixture and the transport from the mixer to the manufacturing plant are not part of this European Standard (see !EN 12151:2007). The equipment for the transport and handling of formed products, other than the integrated transport system, is not covered by this standard. At the time of drafting, machine specific noise test codes for EN 12629-2 to -8 are not available to fulfill the requirements of 5.7.2 and 7.4.2. When they are available, they will be incorporated in these standards. This document is not applicable to machines for the manufacture of constructional products from concrete and/or calcium silicate, which are manufactured before the date of publication of this document by CEN.

Podaja koncepte ter splošne in skupne zahteve za načrtovanje, obratovanje in vzdrževanje takšnih strojev. Ta evropski standard obravnava nevarnosti, navedene v Klavzuli 4, do katerih lahko pride med obratovanjem in vzdrževanjem strojev za izdelavo gradbenih proizvodov iz betona in apnenega peščenca, vključno z vmesniki, kadar se izvajata v skladu z namembnostjo in pod pogoji napačne uporabe, ki jih proizvajalec lahko razumno predvidi. Deli 2 do 8 tega standarda podajajo dodatne posebne zahteve in se morajo zato uporabljati skupaj s tem delom. Priprava zmesi betona in/ali apnenega peščenca ter prevoz od mešalnika do proizvodnega obrata nista del tega evropskega standarda (glej EN 12151:2007). Ta standard ne zajema opreme za prevoz in delo z oblikovanimi proizvodi, ki ni integriran prevozni sistem. V času priprave osnutka preskusne kode za hrup, specifičen za stroje, za EN 12629-2 do -8 še niso bile na voljo za izpolnjevanje zahtev iz točk 5.7.2 in 7.4.2. Ko bodo na voljo, bodo vključene v te standarde.

4 List of significant hazards This clause contains all hazards, as far as they are dealt with in this European Standard, identified by risk assessment significant for this type of machinery and which require action to eliminate or reduce risk. NOTE This standard covers many different type of machines for the manufacturing of products from concrete and calcium-silicate. Therefore, the following requirements correspond to a general risk assessment. When designing a specific machine, the manufacturer needs to make a specific risk assessment to ensure that the machine does not generate different or additional risks and to take the adequate protective measure Detailed description of hazards identified and specific hazards are contained in the specific standards parts 2 to 8. 4.1 Mechanical hazards Mechanical hazards caused by moving parts of the machine and products 4.1.1 Crushing hazards 4.1.2 Shearing hazards 4.1.3 Cutting or severing hazards 4.1.4 Entanglement hazards 4.1.5 Drawing-in or trapping hazards 4.1.6 Impact hazards 4.1.7 High pressure ejection hazards 4.1.8 Slip, trip or fall hazards 4.2 Electrical hazards 4.3 Hazards generated by noise 4.4 Hazards generated by materials and products 4.5 Hazards generated by neglecting ergonomic principles 4.6 Hazards caused by failure of energy supply 5 !!!!Safety requirements and/or protective measures"""" !Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards which are not dealt with by this document." Concerning the design of guards the relevant clauses of !EN 953:1997+A1:2009" shall be observed. Moreover, they shall be fitted as close as possible to hazardous mobile parts taking into account the requirements contained in !EN 349:1993+A1:2008 and EN ISO 13857:2008". NOTE 1 The protective devices stated in this clause were fixed taking into consideration the criteria described in clause 7 of EN 1088:1995.

NOTE 2 Some guarding examples to avoid contact with hazardous parts are described in Annex B. Where it is necessary to see the working process, guards shall be designed to allow visibility e.g. grids, transparent material or electro-sensitive devices. When using electro-sensitive protective devices, the requirements described in !4.2.2 of EN 61496-1:2004", shall be fulfilled. As far as possible guards shall be separated from the noise enclosures. However, these guards can be combined if it is impossible for a person to be present between the guard and the hazardous mobile parts of the machine (see !Table 5 of EN ISO 13857:2008") and if the setting, changing of mould, cleaning and maintenance works can be done easily and safely !(see EN 614-1:2006+A1:2009)". Additional requirements are, if needed, described in the machine specific !EN 12629-2 to -8". !deleted text" 5.1 Mobile parts of power transmission 5.1.1 Mobile parts to which access during the machine operation is not necessary shall be protected by fixed guards according to clause 3.2 of !EN 953:1997+A1:2009" (see B.1). 5.1.2 If the frequency of access to mobile parts of the power transmission does not exceed once a week and if the work can be done without energy supply fixed guards according to 3.2 of !EN 953:1997+A1:2009" shall be fitted. 5.1.3 If the frequency according to 5.1.2 exceeds once a week or if the work cannot be done with energy supply isolated, interlocking guards shall be fitted according to 3.5 of !EN 953:1997+A1:2009" the circuits of which comply with category 3 of EN 954-1:1996 (see B.2). 5.1.4 If the time taken to gain access to the dangerous zone is less than the after-running accrues, interlocking guards with guard locking according to 3.6 of !EN 953:1997+A1:2009" shall be fitted. !!!!5.1.5 Fixed guards, or parts of the machines acting as such, which are not permanently fixed, e.g. by welding, shall be fixed by systems that can be opened or removed only with tools. These guards fixing systems shall remain attached to the guards or to the machinery when the guards are removed. Where possible, fixed guards shall be incapable of remaining in place without their fixings. NOTE This requirement aims to reduce the risk of fixed guards that have been removed, for example, for maintenance purposes, not being replaced or being only partially fixed in place because one or more of the fixings have been lost.
Application of this requirement depends on the manufacturer's assessment of the risk concerned. The requirement applies to any fixed guards that are liable to be removed by the user with a risk of loss of the fixings, for example, to fixed guards that are liable to be removed during routine cleaning, setting or maintenance operations carried out at the place of use. The requirement does not necessarily apply to fixed guards that are only liable to be removed, for example, when the machinery is completely overhauled, is subject to major repairs or is dismantled for transfer to another site." 5.2 Mobile parts taking part in the working process 5.2.1 Mobile parts taking part in the working process and to which access during the operation is not necessary shall be protected by fixed guards according to 3.2 of !EN 953:1997+A1:2009" (see B.1). 5.2.2 If work in the dangerous zones is necessary more than once a week, interlocking guards according to 3.5 of !EN 953:1997+A1:2009" shall be used, the circuits of which shall comply with EN 954-1:1996 (e. g. with two mechanical controllers according to 6.2.2 of EN 1088:1995). !If sensitive protective equipment as defined in 3.26.5 of EN ISO 12100-1:2003 are selected, they shall meet the requirements of EN 61496-1:2004 and give an equivalent level on integrity as described in the previous sentence (see B.2, B.3, B.4)."

Means shall be provided to ascertain that the restraint device is engaged (e.g. marking, notch). Moreover, the restart of the machine shall not be possible as long as this device operates." Where access beneath the suspended parts is required as part of the manufacturing cycle, the restraint device shall be engaged automatically. 5.2.4 If it is possible to enter the danger zone before the mobile parts have come to rest, interlocking guards with guard locking according to 3.6 of !EN 953:1997+A1:2009" shall be fitted. !!!!5.2.5 Fixed guards, or parts of the machines acting as such, which are not permanently fixed, e.g. by welding, shall be fixed by systems that can be opened or removed only with tools. These guards fixing systems shall remain attached to the guards or to the machinery when the guards are removed. Where possible, fixed guards shall be incapable of remaining in place without their fixings.
